Did Norway just give Tesla a big win?

One tweet by Tesla Motors CEO Elon Musk has given fans of electric vehicles the kind of news they never could have imagined just a few years ago.

Musk tweeted out the front page of a Norwegian newspaper "Dagens Naeringsliv" and wrote: "Just heard that Norway will ban sales of fuel cars by 2025. You guys Rock!!"

The Norwegian headline says four political parties have agreed on an energy message: "Stop sales of diesel and gasoline vehicles in 2025."

The question is whether or not Norway has officially signed off on a ban of gas-powered cars nine years from now. While the country offers some of the biggest tax incentives in Europe to buyers of electric vehicles, the majority of cars and vans sold each year are gasoline and diesel powered.

A draft of the country's 2018-2029 National Transport Plan presented this spring set a target of zero emissions from new cars by 2025, according to several media sites. But there's a clear difference between having a goal of zero emissions vehicles and outright banning the sale of gas powered cars.

Norway's auto population is not very big. In fact, its auto sales are among the smallest in Europe, with just over 150,000 cars sold last year.

Still, for any country to completely stop selling new gas and diesel powered vehicles would be a major step toward accelerating adoption of electric vehicles.
